Features

S-UTILS helps in:

manipulating directory pathnames
copying streams
doing some elementary parsing (tokenising)
flexibly formatting dates, times and durations
parsing integers more safely

Status

S-UTILS is considered stable code.

News

November 2005 - Created as a separate project.

Platforms

S-UTILS is written in ANSI standard Common Lisp and should be portable across any CL implementation.

Installation

The S-UTILS package is loaded using ASDF. There is an excellent tutorial on ASDF to get you started.

CL-USER 1 > (asdf:oos 'asdf:load-op :s-utils)

Example of setting up and using ASDF to compile and load the package

Usage

Usage of the functionality in S-UTILS is straightforward, as the following examples demonstrate:

CL-USER 1 > (in-package :s-utils)
#<The S-UTILS package, 41/128 internal, 13/16 external>

S-UTILS 2 > (defvar *timestamp* (get-universal-time))
*TIMESTAMP*

S-UTILS 3 > (format-universal-time *timestamp*)
"Sat Nov 19 2005 18:08:51"

S-UTILS 4 > (format-iso-gmt-time *timestamp*)
"20051119T170851"

S-UTILS 5 > (format-universal-time *timestamp* :format +us-date-format+ :stream t) 
Sat Nov 19 2005
NIL

S-UTILS 6 > (format-universal-time *timestamp* :format +us-time-format+ :timezone 0)
"Sat Nov 19 2005 17:08:51"

S-UTILS 7 > (format-duration (- (get-universal-time) *timestamp*))
"5 minutes 18 seconds"

S-UTILS 8 > (tokens *)
("5" "minutes" "18" "seconds")

S-UTILS 9 > (tokens "1-2-3-4-5" :separators '(#\-))
("1" "2" "3" "4" "5")

S-UTILS 10 > (parse-integer-safely "")
NIL

S-UTILS 11 > (parse-integer-safely "x" :default -1)
-1

S-UTILS 12 > (parse-integer-safely "111" :default 123 :start 2)
1

S-UTILS 13 > (parse-integer-safely "111" :default 123 :start 3)
123

S-UTILS 14 > (parse-integer-safely "" :default -1)
-1

S-UTILS 15 > (parse-integer-safely nil :default -1)
-1

S-UTILS 16 > (parse-integer-safely "FF" :radix 16)
255

S-UTILS 17 > (with-input-from-string (in "abcdefghi")
               (copy-stream in *standard-output*)
               (terpri))
abcdefghi
NIL

S-UTILS 18 > (make-subdirectory #p"/tmp/" '("foo" "bar"))
#P"/tmp/foo/bar/"

S-UTILS 19 > (pathname-parent #p"/tmp/")
#P"/"

S-UTILS 20 > (pathname-parent (make-subdirectory #p"/tmp/" "foo"))
#P"/tmp/"
